I was just playing around with my iPhone (playing around with the themes on winterboard) then I stopped for a while and after getting notifications from the lockscreen, my iPhone froze so I pressed both the lock button and home button to reboot it. Now for the last 10 minutes or so, it's been going through spinning wheel and apple logo phase. I don't want to have to do a restore on it because that would mean I have to rejailbreak it and reinstall all apps and themes all over again. Is there any way to fix this without having to delete all my cydia apps? I am using an iphone 4s on ios 5.1.1.
